Introduction

In this report we will analyze the StackOverflow 2018 and 2023 Survey data. We put our focus on comparisons of different aspects of programmer’s life with respect to salary. In particular, we will explore

Median salary distribution on level of experience

In this section we will compare the distribution of salaries in 2018 and 2023 and ask an important question: do programmers earn more in 2023 than in 2018?

Comparison of the distribution in 2018 and 2023

First, we investigate how salary changed over the six years:

Apart from the obvious fact that salary increases with the experience, we observe and interesting decline in more experienced professionalist.

Inflation between 2018 and 2023

Comparing salaries in 5 years period we cannot forget about inflation. As salaries have been converted to USD by the StackOverflow at the time, we can take only dollar’s inflation into the account

## `geom_smooth()` using method = 'loess' and formula = 'y ~ x'

It’s important to remark that we the the conversion rates between currencies do not depend only Inflation.

Do programmers earn more in 2023 than in 2018?

After consideration we may wonder how the changes relate to the inflation.

The total cumulative inflation betwen 2018 and 2023 was???? 0.242769

We now examine how percentage-wise changes in compensation, compare to the inflation

As we can see, even though the nominal salary increased in for developers up to 23 years of experience, the only group that earns more after these 5 years are new developers.

Admired languages and salary

Now we will examine, if languages that are especially liked by programmers, bring them more income

As we can see we obtain a triangular shape. Langugages, which developers want to use the most, are in the middle of salaries.

On the other hand the less desired languages spread accros the salary ax. On the one hand, systems that use egsotic???? and unpleasent languages, will pay moreto attract employees, and on the other hand …

Is it better to work in big companies?

We wanted to examine if at different stages of professional life it is more worth it to work in small companies or big corporations.

Interestingly, it seems that working in big giants is always most profitable. On the other hand, the more experience you have the more plot buldge around 500-999 employees.

Best paying countries

Of course salary depends greatly on the country you work with.

As shown above, the countries which stand out are USA, switzerland and Australia
